Read/Write signal input is used to select the read/write mode High = Read mode, Low = Write mode
6 E Start enable signal to read or write the data
7~10 DB0 ~ DB3
Four low order bi-directional three-state data bus lines.
Used for data transfer between the MPU and the LCD module.
These four are not used during 4-bit operation.
11~14 DB4 ~ DB7
Four high order bi-directional three-state data bus lines.
Used for data transfer between the MPU and the LCD module.
DB7 can be used as a busy flag.
